A reduction of 20% in the price of salt enabled a purchaser to obtain 4 kg more of Rs. 100. The reduced price of salt per kg is ?

Rs. 4

Rs. 5

Rs. 6.25

Rs. 6.50

In these kind of Questions,

The Price ratio and Quantity ratio will be in reverse proportion.

Price Ratio = 100:80 = 5:4

So Quantity Ratio = 4:5

Now we can buy 4 kg more.

So Difference between the quantities bought in both cases is 4 kg.

=> 5x - 4x = 4 kg

x = 4 kg.

Now we can buy 5x = 5*4 = 20 kg.

Reduced Price = 100 Rs./20 kg = 5 Rs./kg
